MAC地址简介及购买价格


MAC地址(英语:Media Access Control Address),直译为媒体访问控制地址,也称为以太网ID或物理地址,它是一个用来确认网络设备位置的地址。在OSI模型中,第三层网络层负责IP地址,第二层数据链接层则负责MAC地址。MAC地址用于在网络中唯一标示一个网卡,一台设备若有一或多个网卡,则每个网卡都需要并会有一个唯一的MAC地址。

目前,MAC地址只能通过IEEE标准协会直接从美国购买,根据数量的不同,可分为MA-L(可大约生成1600万个地址),MA-M(可大约生成100万个地址)和MA-S(可生成4096个地址)。以MA-L为例,其价格如下 (具体价格以英文网站为准)

购买地址:http://standards.ieee.org/develop/regauth/oui/index.html

如果没有保密需求,只需支付$2,655就可获得一个MA-L,也就是说此类公司的名称和地址是公开的,公众可以访问https://regauth.standards.ieee.org/standards-ra-web/pub/view.html#registries下载查询。如果生产厂商希望对以上信息保密,可以选择Privately registered MA-L,价格为$5,725,且每年需要支付保密费用$3,070。
如需购买,按照要求建立公司账户,填写公司信息,选择付款方式,最后在线提交订单。成功提交订单后,账户中会生成一个Invoice,待美国收到支付款项后,系统中还会生成一个Cover Letter。

注:保密的价格较高,不保密的价格不是太贵。如下为官网价格:
